Carb advice needed..

[Midnight Sun]

I've just finished the first gallon of Magnum 12% through the OS 32 in my Raptor.

I've now bought 20% Magnum which is probably what I'll stay with whilst learning as the throttle did not seem all that responsive. Maybe that is more to do with the small engine size or maybe its too rich as it smokes like hell. The engine does chatter and 4 stroke a bit when cold at idle but that clears as the engine comes on song at higher revs.

Will I need to do much adjustment on the carb setting with the 20% and if so what settings should I go to ?

Any advice would be gratefully received.

Thanks.

Bring it up to dmhc today, will run you through the basics of engine tuning and getting it running spot on. probably no need for 20%

engine tuning is a bit of an art and quite difficult to teach over a forum!

Ade, thanks for the offer. What time will you be there ? I have some serious negotiations to do with the other half as I'd promised a trip to Lyme Regis......Trying to change the destination to Wimborne in light of your kind offer...
I've just had a plastic ball link come off the throttle and burn out on the exhaust pipe. Do you have a spare I could beg steal or borrow ?
